DOFFER GUARD AND OIL-WELL COVER FOR LIKE TKAGHINES.

Specification of Letters Patent.

Patented Aug. 15, 1922.

Application filed June 8, 1921. Serial No. 475,915.

To all whom it may concern Be it known that we, JosnrH B. GLENNON andLorns Dorms, citizens of the United States, residing at New Bedford, inthe county of Bristol and State of Massachusetts, have invented new anduseful Improvements in Doffer Guards and Oil-Well Covers for SpindleSupports for Spinning and like Machines, of which the following is aspecification.

The present invention relates to spindles for spinning machines, andparticularly to doffer guards for retaining the spindle in the bolster.It contemplates a combined doffer guard and oil well cover, so assembledand disposed as that the doiier guard will be locked against accidentalshifting or displacement, and yet may be readily shifted by an operatorto permit removal of the spindle from its bolster.

The construction is such as to minimize danger of breakage of any of theparts and to eliminate danger of breakage of the bolster casing or theoil well post, all likelihood of breakage being confined to the doiferguard and oil well cover which, under the present construction, may bevery quickly and readily replaced at small expense.

Broadly, it is old to provide dofier guards and oil well covers socombined as to prevent accidental unshipping of the spindles inoperation, and at the same time protect the oil wells, and we do notclaim broadly this as our invention, as the same general idea has beenworked out in variousconstructions, but the present development hascertain features of novelty and certain advantages over doffer guardsnow known to us, due to the construction and assemblage which we haveinvented.

In order that the invention may be clear to those skilled in the art, wehave shown in the accompanying drawings one physical embodiment of ourinvention, but it will be understood that this is illustrative and notrestrictive, as such changes as are merely equivalent mechanicalexpedients, and such departures as are obvious variations of theconstruction herein disclosed may be made without going outside therange of our invention.

In said drawings:

Figure 1 is an elevation of a bolster oasing with so much of a spindlethereon as is necessary to an understanding of our invention, the dofierguard being shown in oper ative position.

Figure 2 is an elevation similar to Fig. 1, the doifer guard being shownin its inoperative position.

Figure 3 is a plan view of the mechanism with the parts 1n the positionshown in Fig. 1.

Figure 4: is a plan view of the mechanism with the parts in the positionshown in Fig. 2.

Figure 5 is an elevation at right angles to and looking from the rightof Fig. 1.

igure 6 is a view at right angles to and looking from the right of Fig.2.

Figure 7 is a detail perspective view of the oil well cap.

Figure 8 is a detail perspective view of the oil well cap supportingpost.

Referring to the drawings by numerals, like numbers indicating likeparts in the several views, 10 designates a bolster casing of anyordinary or usual construction, and 11 indicates any ordinary spindlewith the whorl 12, arranged in the usual manner.

The bolster casing 10 has the usual body portion or flange 13 whichseats upon the bolster rail and from the body 18 projects the oilreservoir which delivers to the bolster casing, said oil reservoirhaving a horizontal section it delivering to the casing and the verticalreservoir or receiving section 15 which has an open top to permitfilling or oiling.

The parts thus far described are old and well known in the art.

The oil well post 15 is provided with an enlarged section 16 on itsinner side adiacent the whorl 12, this enlargement 16 being of a size toprovide an area in which is formed a receiving socket 17, which socketis of sufficient depth and so formed, as, for example, byscrew-threading, as to re ceive and retain the vertical limb 18 of asubstantially L-shaped dofi'er guard, the horizontal limb 19 of whichguard is of sufiicient length to project inwardly over the ativeposition shown in whorl 12 when the guard is in the position shown inFigures 1, 3 and 5.

This guard may be readily formed by bending a piece of heavy wire orsmall rod, and screw threading or otherwise fashioning the vertical limb18 of the guard to lit the socket 17 and be retained therein, but freelyrotatable to permitthe guard from the operative position shown in Figure1 to the inoperative position shown in Fig ure 2, so that an effectivedoifeguard,;operative to engage the whorl 12 when in one position, andcapable of being'thrown to an inoperative position, as shown in Figures2, 4, and 6, to permit removal of the spindle, is provided.

The horizontal section 19 of the L-shaped guard is provided with an oilwell cover '20, the forks or arms of which straddle the horizontal limb19 of the guard as shown clearly in Figures 3 and 4, and are preferablypinned thereto by the pivot pin 21, so that the cover 20 is free toswing from the full line position shown in Figure 1, to an anglerelative to the guard, as indicated 'by dotted lines in Figure 1. i I

The oil well cover 20 has at its forward covering end the enlargedportion, of sufficient area to cover the oil hole in the vertical memberor oil post 15, and is provided with means for locking the cover and theL-shaped guard against angular movement or rotation when such oil wellcover is in its closed position, as shown in full lines in Figures 1, 3and 5. The particular means here shown'for locking the parts againstangular movement comprises the flanges 22, which depend from the freeend of the cover20 and, when it is in closed position, straddle the oilWellpost 15 and engage on either side thereof, so that lateral movementof the cover and its supporting post in either direction is impossible.This prevents any accidental shifting of the parts, and the L-shapeddoffer guard can be swung to the inoper- Figure 2, only after the 'oilwell cover 20 has been tilted to clear the flanges 22 from engagementwith the top of the oil well posts. This effectually prevents anyshifting of the parts except when the operators manipulate them for thepurpose of removing or replacing spindles in the bolster casings.

It will be observed that with this con struction, the Lrshaped memberforms a very substantial and effective doffer guard, that L-shapedmember taking the strain of impact from the whorl 12 either during thespinning operation or during dofiing, and prevents unshipping ofspindles due to vertical *lift during running or during the removal ofcops from the spindles. At the same time, a guard is provided which maybe very easily and quickly shifted by sim ply raising the oil well coverto clear the to be shifted a spindle whorl,

her that it will accommodate itself to a relatively wide range ofvertical adjustments of the member or guard, the slot between the forksof the cover being of sufficient length to give clearance and permit thecover plate to take its position on the oil well post 15 with itsflanges 22 in en gagement therewith regardless of the verticaladjustment ofthe dotfer guard.

It will be observed that the L-shaped member or guard, which may be madeof material of suflicien't strength to resist breakage under ordinaryimpact, sustains the entire force of the blow of the whorl and sincethis is separately formed from the oil well post and oil well cover, ifbreakage should occur, it will be breakage of the L-shaped guard, wellcover and the oil post, which is formed integral with the bolstercasing, in condition for use, and replacement of the entire bolstercasing or the oil well cover is done away with, the only repairnecessary being the replacement of the relatively small, inexpensive,L-shaped dofl'er guard.

lit will be understood that the invention can be applied to any spindleregardless of type or work done, to which it may be adapted, to securethe results hereinbefore described, and we do not limit ourselves to anyspecific type of spindle.
